Here are the salvaged brake pieces compared to the book Daryl Demerchant dug up a while back (Nov. 21, 2003 post). I took quite a bit of time trying to illustrate what appears to be a match between our salvaged brake pieces VS actual technical brake specifications commonly found on steam locomotives of that era. The specs were from a book titled "Locomotive Engineering" published in 1908. Page 566 shows the brake specifications. These pieces were found at the sand mound.
